To all whom may concern;

I, VINCENT LOMEARXYE, a citizen of the United States, residing atBrooklyn, in the county of Kings, State of New York, have inventedcertain new and useful improvements in Knitting Machines, of which thefollowing is a full, clear, concise, and exact description.

This invention relates to knitting I113 chines and methods, and moreparticularly it relates to machines and methods, ttor knit tingmniti-color fabrics.

An object 'of-this inventionis to provide automatic n eans forilmittinga Inulti-color fabric in ivhich different portions of the fabric will heof different colors, the yarn which does not determine the color 0 thefront of the cloth in any particular portion being carried along withthe knitting but substantially concealed from the front of the fabric.

Another ohjectis to provide adjustable income in a knitting machine forvarying the pattern of the fabric at any time desired.

Another object is to provide means for producing a predeterminedvariation in the rise and fall olthe needles of a knitting machine tocause desired. variations in the fabric.

Another object is'to provide for causing certain needles. to rise atparticular times while allowing neighboring needles to remain in theirlowest positions.

Another object is to nrovide a ias-chine for knitting a two-color tahricin which the yarn not in loops will be interlocked he.- hind and betweenthe loops of the other yarn;

Still another object is to provide an improved method of knittingwhereby the re,- suits outlined above may be accomplished.

Other objects of the invention will in part be obvious and will in partappear hereinafter.

One form of this invention will he hereinafter described in detail. inconnection with a circular knitting machine for knitting multi-colorfabrics, In this machine the above objects are attained by providingfour diil'erent kinds of needles in case the machine is for two-colorknitting. \Two types have butts at. the same relative position alongtheir shanks, but the butts i i one type are short and in the other,long. T two types are also characterized h long and short butts with thebut .3

in relative position compared to the first two types. This enables theneedles having butts at one height to be operated by cams independent ofother coins for opcrating the needles having butts at the other height.A further distinction can he made by coins of diti'erent sizes foroperating'only the needles with long butts or all the needles. Theemployment of four kinds of needles is or" course only one way in. whichmeans may he provided for selectively-"op crating the needles in apredetermined manner.

In locating the needles in a circular knitting machine those placeswhere it is desired that the fabric be one of the colors, the needleshaving butts of one height are placed, the long and the short buttsbeing alternated. At the other places where the fabric is to be of theother color the needles having butts at the other height are placed,

he other 'the long and short butts being alternated Suitable camsurfaces are provided for bringing all of the needles for one color upto form loops when that color yarn is pass ing while when the other yarnis passing alternate ones of these needles are partially raised stillkeeping their latches open and keeping the last formed loop around boththe needle and the open latch. After the yarn of the second color ishooked by these partially raised needles they are lowered again, vi henthe first yarn comes around again all of the needles for the first colorare fully raised in turn to allow each old loop ofthe first. color andthe alternately hooked. yarn of the second color to slip-ha low thelatch so that when each of these needles is lowered the old loops andthe hooked yarn of the second color will slip over the tops of theneedles and be replaced by the newly formed loops. This results in theyarn of the second color being interlocked behind the loops of othercolor, there" by providing a closely knitted fabric which does not haveany loose dangling loops on the back side of the fabric which inprevious fabrics were sources of constant trouble because of theliability of their being.

snagged and the yarnhroken, thereby destroying the fabric. The yarn ofthe secondoolor inthe machine'of this invention is in 73. The oddnumbered'need'les have {short the above manner locked between the loopsbutts as shown at 55and 58,. while the-even of'the first yarn withoutchanging however numbered have long b-utts'as at 56 and 57.toanysubstantial degree the appearance of Forconvenicnce ii1 .'-ig..,1.the longlmtts are 1 thefront-of the fabric. r l shown shaded while theshort butts are-una The above described operation of the shaded in ordertogrca dily distinguishthe p needles for one color is repeated by otherkinds of needles.

1,541,230 y is' Needle 1 will not be lifted by cam 61 but will remainwith its butt along surface 71 similar to needles 3, 5, I, .9, etc. jThe'needle 2 however with a long butt will be raised by cam 61 and willsuccessively take positions similar to needles 4, 6, 8, etc. Needle 2when raised by cam 61 will not be raised to its maximum top positionbutwilL be raised an amount sufiicient to allow the latch to open and havethe loop surround both the shank and the latch but not raised far enoughto allow the loop to slip over the end of the latch. The even numberedneedles from 1 to 14 are then partially raised by cam 61 while the oddnumbered ones re main in their lowermost positions.

Cum 62 will next strike the needles 1 to 14 and the cam is of sufficientwidth to lower both the long butt needles and short butt needles.However. since only the long buttneedles of 1 to 14 have been raised itfollows that only the long butt needles of l to 14 will be lowered bycam 62. The revolving cylinder carrying the cams also supports andcarries along with it the yarn carriers shown in detail in subsequentfigures. Located just above cam 62 is the yarn carrier for black yarn 84so that thelong butt needles of 1 to 1 1- will be lowered by cam 62after black yarn 84 has been hooked by them. After the long butt needlesof 1 to 1.4 are lowered by cam 62 they will be positioned the same asneedles 26 to 29. The s ort butt needles 27 and 29 which were not aisedby cam 61 nor lowered by cam 62 have their latches closed and containinftheir closed latches loops ofthe white yarn previously made. The longbutt, needles 26 and 28 which were pulled down by cam (32 have theirlatches still open but with each book containing both a loop of thewhite yarn and the straight portion of the black yarn within the hookand just above the White loop. The straight portion of the black yarnwill lie on top of the short butt needles such as 27 and 29.

The next corn to ali'ect the needles having butts between surfaces 70and .71 is cam 6:3 which is of such a width as to, "raise only the longbutt needles to the position shown for needles 32 and 34. This is againonly a partially raiscd condition suchas that 'produced by cam 61. abovedescribed. It will be noted that due tothe raising of the long buttneedles by cam 63 the long butt needles each has (as shown atS l) itslatch open I with the loop of white yarn as well as the straight part ofthe black yarn on the side of the needle adjacent the observer while theblack yarn still remains above the closed latches of the short buttneedles as shown The next cam to operate the needles having buttsbetween surfaces 70 and 71. is cam .64 which isof such a thickness as toraise 4 both the short and long butt needles and to raise them to theirmaximum height. (lam 64 thereby puts the needles in positions similar to43, 44, and since cam 64 in raisingthe long butt needles will allow theloop of unlooped black yarn to follow a Zig zag path in front ofalternate needles and behind the remaining needles for a purposedescribed. later.

The next cam to operate the needles be tween surfaces 70 and 71 is cam65 which will meet both the shortbutt and long butt needles in theiruppermost positions with all latches open and will lower both types.Supported immediately above the cam 65 is the carrier for the white yarn83 which carrier of course rotates with the ams. The yarn 83 will thcnbecaught by these needles as they are lowered, each latch will be closedby theformer loop bearing upwards against it and after each needle hasreached near its lowermost position each old loop will slip over theclosed latch of the needle and over the edge of the fixed cylinder sothat when the needle has reached its lowermost position only the newloop is around the needle. Due to the fact ",that the black yarn is onone side of the long butt needles and the opposite side of the shortbutt needles the black yarn for each long butt needle will slip over theend of the needle and will lie beside the end of the old loop and acrossboth parts of the new loop as will appear from the position of needle 54in Fig. 2. The fabric shown in Fig. 2 is shown of course with the backside to the observer. For the loops formed by the long butt needles theblack yarn just slipped over each needle by cam will lie entirely behindeach loop formed thereby. For the short butt needles however the blackyarn is already on the side of the needle opposite the observer so thatwhen the old loop is slipped over a short butt ncedleby cam 65 and thewhite yarn is pulled through the old loop to form a new loop theblaclvyarn is caught and locked between the new and old loops as shownfor example by the fabric opposite needle 53 of Fig. 2. The exact natureof thepath taken by the black yarn through the white yarn loops will bebetter understood by reference to Figs. 12 13 and 1 a cycle begun by thecam 61 so that the i3" needles after being lowered by cam d5- are whiteyarn and the blackyarn to slip bc 3' ready to be 'operat'ed again byearns. 61 2,

-'63," 6 4 and 65'. in the order named". to term 'a vnewi'o'wofavhitef'yarn loops.

The above description has shown how the white yarn loops 'aref'formed+Tha't portion .of the fabric knitted by needles 1 to 14; 21

73, the even nlllllbfll'ed needleshaving long (311111.76 corresponds tocam 61 tot raise the lon'g butt needles. After this selective. railsingtlie neeidles encounteream '17 whichco rresponds to canr62 to .causethe whfltezyarn to becaught by alternate needles withopen latcheseven-after ,they are lowered by cam 77- .Aft'er the passage otcam 7 7needles 35 to 40would'1ook like needles 2- to with the yarns reversed ofcourse. Gain 77 isof suflicient width to lower both the long butt.needles and the 'short'butt needles, but for the arrangement shown withcam 79 not 30.

operatingonly the long butt needles are lowered. After cam 77 has passedthe next cam is'7ft of such'wwidth as to selectively raise only the longbutt needles. For the particular arrangement shown this selectivity isnot utilized since with cam 78 in the position shown both the long buttand short butt needles will befully raised thereby.

."l-heseneedlcs neat encounter cam 75 which corresponds to cam forcatching the black yarn and, forming new loops, the white yarn beinginterlocked between the black loops in just .tbe same manner asdescribed for the white loops. After cam is encountered-tho next cam is70 and the above described cycle will be repeated as often as. desired.

It thus will be seen {that the needles 1 to 14,21 mat, and 41 to at willknit white loops with the black yarn on the back side of the fabric butinterlocked in alternate loops, while needles 15 to '20 and 35 to 40knit black loops with the white yarn 0n the backside of the:fabric'in'terlocked -in.alter-' and8l are'of coursemerely illustrativeas the two ya'rns may be of any desired colors 3 ormay be of the samecolor but differing in. some other characteristic.

This reversal of cams 64:, 66,79 and 7.8

therefore results in the blaclryarn being knitted where the ,white yarnformerly. was

and-the white yarn. lgnitted where the black was. After several rowshavebeen knitted in this manner-cams 64, 66, '38 and Y9 t e be replaced inthe positions shown in Fig whereby the col scheme will be reversedagain.- T-his'cha "ging of the four adjustable cams thereforeenables afabric to be knitted re embling a checker, board in color mafia H Inviewof theabore explanations itwill be apparentthatl'if it is desiredtoinake several ,white rows entirely around the fab 11C,' c'ams 64: and79 should be raised-into desired around the-whole cloth :both casesoperativepositi ons" while cams (3 6 and 78 should be inoperative. Onthe other hand, u if'an entirely black row or rows of loops is shown. Asuitable stop member 112 limits' the upward movement. of the pivoted arm'j105 In order to maintain the arm 105 'in {its uppermost" positionafter disc 4 108 hasbeen passed a spring member 113 is 'madej-fto rideover a curved surface 114 server; tospring outward the 114 adjacent stop112 which is suitably supported .by revolving cylinder 91 from apointnot shown in the sectional view of Fig. 3.

The manner in which the cylinder 91 may be revolved is not material tothis invention ut may be accomplished in any of the ways known in theart. For example thelower side of base plate 92 may be provided withteeth which cooperate with a cog wheel to rotate the cylinder. The copwheel (not shown) may be connected to a source of power such asdetermined links-, a plurality of cams such socket joint the revolving'cylind 1'1 9,'while I Q or disc'shouid be pivoted-above theother'piwLee-1.230

The manner in which the and may be raised or lowerec maybe understoodfrom Fig. 4 which is a side view of the machine taken near :the crosssection, of Fig. 2. The'lower end of support pivoted to a horizontal armpivoted at 124 and at the end 0 posit'e the j pivot is adapted to beheld'up by; latch-.7 125 which is pressed against the..arm' 128 -f by aspring 126.

However as soon as wheel 136 has revolved to a sullicient extent thateam 131 .is operative to raise arm 128 and lower arm 123 as abovedescribed cams 64 and 78 will be inoperative and cams 66 and 79 will beoperative.

Wheel 136 should preferably he geared tothe mechanism driving the revolving cylinder 93' so that chain 129 movesalong one link for a dciinitc number of complete revolutions of thecylinder 93.

At certain places along the chain it may be desired to have anattachment such as that shown in Fig. 9 which has no projectionsullicient to raise either arm 12 5 or 128,but merely has a horizontalprojection 13? extending away from the chain on the side opposite theobserver. when it has reached the position shown for earn 130 in if" 4will contact with a special control arm m8 and tend to raise the same.This control arm is supported by the pivoted latch 125 at one end and bya pivoted member lilt at the other end.

From the above description it will be apparent that with both arms 121-and 128 raised all cams 64, 3.6:, 1 8 anri'ill Ni 1 be operated so thatboth types of needles knit not only black-loops but White loops as well.

'ih'c'fabric. ascxemplilicd in Fig. 12. compriscs a left-hand portion, in which the.black yarn is looped. and a right-hand portion, in which the white yarnis looped, three of the wales of the. black yarn being shown at n. b andc, and tour of the wales ot' the white yarn being shown at (l, o. f and5 In this particular fabric, the unlooped portion of the white. yarn isinterlocked with the black yarn in the ales a and 0. and is carriedentirely to the rear of the black yarn in the wale Z1; while theunlooped tion of the black yarnis interlocked withthe loops oi the whiteyarn in the wales d and'f. and is carried entirely to the rear of thewhite yarn-in the wales c and g.

An arrangement of this type w'herein the unlooped portions ofthe y'arnsare interlocked in alternate wales of the looped portions oitheotheryarns, gives a maximum of interlocking, while preventing theformation of dangling loops so frequently present on the inside of atwo-color knitted fabric; the fabric knitted byithe present inventionhaving no dangling loops, even at the point between the wales and d,wheret'he color ofthe front of the fabric changes. It will 1 .benotedthat the fabric shown in Fig. 12 is ample, a fabric-of the somewhatdifferent from the fabric shown in Fig. 2, in that there is an'interlock at each of the adjacent wales of different colors 0 and (l;whereas in the fabric shown in Fig. 2. therewould be an interlock onlyatone of :these wales, the next interlock occurring in a wale whichwould correspond to"the wale e. It will thus be obvious that fabricshaving a variety of interlocking arrangements may be produced by thepresent invention, all of which are nevertheless substantially similarand capable of being readily produced by a machine of thetypeillustrated. For 'cx character illustrated in Fig. 12 mightbeproduced by e series of needles arrangedas in-Fig. 1, except. that]the needles 20 and 40 would be omitted. Still another; arrangementmight-be produced by the omission of the needles 21 and41.

It will be observed from Fig. let'that the black yarn is very tightlydrawn so that very little thereof is visible from the front of thatportion of the fabric fwh'ereintbc white yarn 'is looped. Thus there isprov duced a fabric wherein the unlooped portion does not substantiallyaffect the character of the front of the fabric. It will, of course, be.obvious that there maybe produced by the present invention types, andfabrics in which the'yarns c0nstituting the samemay "be more or lesstightly drawn according'to the type of fabric which it', is desired toproduce.

It will be apparent from the above dcscription that the two color fabricis kniticd without the rcqnircmcnt of the 'so-callcd- I v 78 and 79 areas in the of the yarn; while being securely interlocked,

In an independent needle machine for combining a plurality of yarnsinto a fabric, in combination, a plurality of yarn feeds for independentyarns, a row of, needles, means cooperating with said needles tomanipulate said yarns to form a series of rows of interknitted loops ofcertain of said yarns inoue'sect-ion of the fabric and to interlockunlooped portions of certain other of said yarns between loops inadjacent rows nally of certain of the wales of the first sec? iae saidcertain of said yarns tion and to interlock unlooped portions of betweenloops in adjacent rows in alternate wales thereof, and to form a seriesof rows of interknitted loops of said certain of said tion of the.fabric disposed longitudinally of certain of the Wales ot' said secondsection, and to interlock unlooped portions o' said certain other ofsaid yarns between loops in adjacent rows in alternate \vales thereof.

28. In a machine for incorporating a plurality of independent yarns intoa fabric, a row of needles, means to impart longitudinal movement tosaid needles to cause a pinrality of adjacent needles to knit loops orcertain of said yarns and to interlock unlooped portions of certainother of said yarns therewith and to cause a plurality of other adjacentneedles to knit' loops of said certain other of said yarns and tointerlock certain of said yarns therewith, said means comprisingadjustable members whereby the particular needles knitting loops of eachof said yarns may be varied, and means adapted to be operatedcontinuously to cilcct an adjustment of said adjustable members fromtime to time.

The method of combining into a tabric the yarns carried by a pluralityol' yarn feeds, which comprises placing all of a group'of adjacentmembers oi" a row o knitting needles in an advanced position to receiveya, 1 at one of said l'ceds, placing only certain of the needles ofanother group in an advanced position to receive yarn at said teed,placing all the needles ol said other group in an advanced position toreceive yarn at a second of said 5 eeds. am placing only certain of theneedles of the lirst group in an advanced position to receive yarn atsaid second feed.

30. The method of combining a plurality o'li independent yarns into afabric which con'iprises caus ng a group ot ndpiccnt,

members of a rovv oi knitting needles to be fully advanced to receiveone of said yarns, causing alternate needles of a secoi'id group to be,partially advanced to receive said yarn, while the remainder of theneedles of said second group are in a retracted position, and retractingthe advanced needles, and thereafter cihlsing all the needles of asecond group to be fully advanced to re.- ceive another/lot said yarns,causing alternate needles .oF the l'irst group to be partially advancedto receive, said other yarn, while the remainder of the needles of theiirst group aredn arctracted position, and retracting the advancedneedles.

ill. The method of combining into a fabric the yarns clllr led by aplurality of yarn feeds which cempriscs advancing and retracting a.grotiip oi latched needles to cause them to catch iihe yarnat one ol'said l'ccds yarns in a sec-- and to knit loops thereof, subsequentlyadvancing certain of the needles of said group a distance sufficient tocatch the yarn at a second of said feeds but insufficient to permit theyarn previously caught to escape from. the latches thereof andretracting the same, and thereafter again advancing lll'lt retractingall the needles of said group to catch the yarn at client said feeds andto knit loops thereof; substantially simultaneously' advancing andretracting all the needles of a second group to catch the yarn. at saidsecond feed and to knit loops thereof, subsequently advancing certain oft e needles ot' said second group a distancesuftieient to catch the yarnat the first, mentioned feed but insufficient to permit the urnpreviously caught to escape from the latches thereof and retracting thesame an thereafter advancing and retracting all the needles of saidsecond group to cause them to catch the yarn at one of said feeds and toknit loops thereof;- and at a later period of operation advancing andretracting all.-

the needles of the first group to cause them to catch the yarn at saidsecond feed, subsequently advancing certain needles of said first groupa distance sufiicient to catch the yarn at the first mentioned feed butinsufficient to permit the yarn previously caught to escape from thelatches thereof and retracting the same, and thereafter again advancingand retracting all the needles 0 said lirstgroup to catch the yarn atone Of said l'eeds and to knit loops thereof; and substantiallysimultaneously advancing an retracting all the needles of said secondgroup to catch the yarn at the first mentioned feed and seouentlyadvancing certain needles in said second group a distance sullieicnt tocatch the yarn at said second food but insullicient to prevent the yarn'previously caught to escape from the latches thereof and retracting thesame and thereafter advancing and retracting all the needles of thesecond group to cause them to catch 'the yarn at one of said feeds andto knit lo'o ps thereof.

The method of knitting into a, fabric the yarns carried by a pluralityof yarn carriers, which comprises advancing -an retracting a group oflatched needles to cause them to catch the yarn carried by one rot saidyarn carriers and to knit loops thereof, subsequently advancingalternate needles of said group a distance sufficient to catch'the yarncarried by a second oi said yarn carriers but insuflicient to permit theyarn previously caught to escape from the latches thereof and retractingthe same, and thereafter again advancing and retracting all the needlesof said group to catch a yarn from one oi said yarn carriers and to knitloops thereof, and substantially simultato knit loops thereof, sub-'lIlO
